UX Designer / Product Designer - £88K - Global Tech

Senior UX / Product Designer - Contract | Central London

A rare contract -PAYE seat has opened on the design team behind advertising and monetisation products used by businesses at global scale. £88,000 - and the work earns it.

This isn't consumer app design. You'll be shaping complex, data-dense tools, the kind where the craft isn't in making things look pretty, it's in making something genuinely intricate feel obvious. Small senior team, one seat, and a high bar for who fills it.

What you'll be doing

• Owning design end to end - turning real, messy user needs into clear journeys, mock-ups and prototypes that actually get built.
• Working closely with UX researchers to design for what users need, not what we assume they need.
• Sitting shoulder to shoulder with product and engineering, staying in the detail so what ships is what you drew.
• Helping the design system grow, so good decisions get made once and reused.
• Designing across both desktop and mobile.

What you'll bring

• 4-6 years in UX, product or interaction design, on complex or enterprise-grade tools rather than purely consumer work.
• Real depth in Figma - it's where you'll live.
• A portfolio that shows your thinking, not just your screens. Strong complex-tooling work from any domain counts; it needn't be advertising.
• Systems thinking, and the knack for explaining a thorny problem - and your way through it - so designers and non-designers both follow you.
• A working command of user-research practices.
• A degree in design, UX or a related product field.
• The kind of person a small team is glad to have in the room. Here, how you collaborate counts as much as how you design.

The Offer:

• Attractive Annual Salary up to £88,000 per year
• 10-month contract (PAYE) to begin with, with real scope to extend
• Hybrid - 3 days a week on-site in central London - Tues, Wed, Thursday
• Inside IR35, PAYE, paid weekly through Principle HR

We're running a short, sharp process on this one - small shortlist, quick decisions, so you won't be left waiting weeks to hear back. If it's a fit, get your application in and I'll come straight back to you.
